IP protection rating
IP is an acronym for Ingress Protection. The IP rating is the needle bai for electrical equipment housing stoking foreign body du, the zhi source is the International Electrotechnical Commission standard IEC 60529. This standard in dao 2004 was also adopted as the United States national standard .
In this standard, for the protection of electrical equipment shell against foreign bodies. THE FORMAT of the IP rating is IPXX. Where XX is two Arabic numerals, the first mark number indicates contact protection and foreign protection level. The second mark number indicates the waterproof protection level, the specific level of protection can refer to the table below.
IP is the international code of the ip rating used to determine the level of protection is composed of two numbers, the first number represents dust protection, and the second number is made of waterproof, the larger the number indicates that the better its protection and other group leader.
Dust level. Number Degree of Protection Definition. 0 No protection No special protection.
1 Prevent the intrusion of objects greater than 50mm. To prevent the human body from accidentally touching parts inside the lamp.
2 Prevent objects larger than 12mm from invading The finger the inside part of the lamp.
3 Prevent full intrusion of objects greater than 2.5mm To prevent the intrusion of tools, wires or objects larger than 2.5mm in diameter.
4 Prevent the intrusion of objects greater than 1.0mm To prevent the intrusion of mosquito flies, insects or objects larger than 1.0.
5 Dust protection does not completely prevent dust intrusion, but the amount of dust intrusion will not affect the proper operation of the lamp.
6 Dust-proof completely prevents dust intrusion.
Number Degree of Protection Definition.
0 No protection No special protection.
1 Prevent dripping from intrusion To prevent vertical droplets.
2 Still prevent drips from intrusion when tilting 15 degrees When the luminaire tilts 15 degrees, it still prevents dripping.
3 Prevent the injection of water from invading The water sprayed by rainwater, or vertical entry angle less than 50 degrees.
4 Prevent splashing water from intrusion To prevent the intrusion of splashed water from all parties.
5 Prevent large waves of water from intrusion To prevent the rapid injection of water from large waves or water vents.
6 Prevent large waves of water intrusion. The lamp can still ensure the normal operation of the lamp under a certain period of time.
7 Prevent water intrusion The lamp’s indefinite sinking water under certain water pressure conditions, and ensure the normal operation of the lamp.
8 Prevent the effects of sinking. The IP (INTERNATIONAL PROTECTION) rating is based on the criteria on which: 1) International Standards for Protection and Waterproofing, drafted by iEC (INTERNATIONAL ELECTROTECHNICAL COMMISSION): IEC 529-598. 2) National standard GB 700-86.3 ) GB 4208, etc.
IP-grade laboratory: At present, the laboratory that can carry out IP-grade testing mainly has the environmental reliability and electromagnetic compatibility test center, the space environment reliability test and test center.
